TECHNICAL FIELD

The present invention relates to novel tricyclic pyrimidine compounds and tricyclic pyridine compounds having JAK inhibitory activities.

BACKGROUND ART

The JAK (Janus kinase) family is a tyrosine kinase family consisting of four members, JAK1, JAK2, JAK3 and Tyk2 (Tyrosine kinase 2) and plays an important role in cytokine signaling.

While the kinases of this family, except for JAK3, are widely expressed in tissues, expression of JAK3 is restricted to immune cells. This is consistent with the fact that JAK3 plays an important role in various receptor-mediated signaling pathways such as IL (interleukin)-2, IL-4, IL-7, IL-9, IL-15 and IL-21 signaling by noncovalently associating with the common γ chain (Non-Patent Documents 1 and 2).

Lowered JAK3 protein levels or defects in the common γ chain gene observed in patients with an immunodeficiency called X-linked Severe Combined Immuno Defficiency (XSCID) suggest that blocking of the JAK3 signaling pathway leads to immunosuppression (Non-Patent Documents 3 and 4). Animal experiments indicate the importance of JAK3 not only in maturation of B- and T-lymphocytes but also in maintenance of T-lymphocyte functions. Therefore, regulation of immune responses via this mechanism is a promising therapy for T-cell lymphoproliferative diseases such as organ transplant rejection and autoimmune diseases.

Analyses of JAK1 knockout mice and JAK1-deficient cells suggest involvement of JAK1 in various receptor-mediated signaling pathways such as IFN (Interferon)α, IFNβ, IFNγ, IL-2, IL-4, IL-6, IL-7 and IL-15 signaling (Non-Patent Document 5). Therefore, regulation of inflammatory responses via these signaling pathways is therapeutically promising for treatment of diseases involving macrophage and lymphocyte activation such as autoimmune diseases and acute and chronic organ transplant rejection.

Analyses of JAK2 knockout mice and JAK2-deficient cells suggest involvement of JAK2 in various receptor-mediated signaling pathways such as EPO (Erythropoietin) α, thrombopoietin, IFNγ, IL-3 and GM-CSF signaling (Non-Patent Documents 6, 7 and 8). These signaling pathways are supposed to mediate differentiation of erythrocyte or thrombocyte progenitor cells in bone marrow. Meanwhile, it is suggested that a substitution of phenylalanine-617 with valine in JAK2 is associated with myeloproliferative diseases (Non-Patent Document 6). Therefore, regulation of differentiation of myeloid progenitor cells via these signaling pathways is therapeutically promising for treatment of myeloproliferative diseases.

The JAK inhibitor CP-690,550 is reported to have improved the pathology of rheumatoid arthritis and psoriasis in clinical tests (Non-Patent Documents 9 and 10) and suppressed rejection in a monkey model of kidney transplantation and airway inflammation in a murine asthma model (Non-Patent Documents 11 and 12). From these findings, immunosuppression by JAK inhibitors is considered to be useful for prevention or treatment of organ transplant rejection and post-transplant graft-versus-host reaction, autoimmune diseases and allergic diseases. Although other compounds having JAK inhibitory action than CP-690,550 have been reported (Patent Documents 1 to 11), development of more of such compounds is demanded.

ASSAY EXAMPLE ^(a) 1 Enzyme Assay

JAK1, JAK2, JAK3 and Tyk2 were purchased from Carna Biosciences, Inc. As the substrate, LANCE Ultra ULight-JAK1 Peptide (manufactured by PerkinElmer Co., Ltd. (PE)) was used. Dilute solutions of compounds and enzymes in assay buffer (50 mM HEPES pH7.5, 1 mM EGTA, 1 mM MgCl₂, 2 mM DTT, 0.01% Tween20) were dispensed into wells of a 384-well black plate. After 5 minutes of preincubation, dilute solutions of the substrate and ATP (adenosine triphosphate) were added at a final concentration of 100 μM, and the plate was incubated at room temperature for 2 hours. After addition of a termination reagent containing EDTA (ethylenediamine tetraacetic acid) at a final concentration of 10 mM, LANCE Eu-W1024 Anti-phosphotyrosine (PT66) (manufactured by PE) was added, and after 1 hour of incubation, the fluorescences were measured with ARVO-HTS. From the plot of logarithm of a compound concentration and inhibitory activity, the IC₅₀ was calculated. The results of JAK3, JAK1, JAK2 and Tyk2 enzyme assays of the compounds of Synthetic Examples^(a) are shown in Tables^(a) 152 to 155. “*” in the Tables indicates IC₅₀>1 μM.

The tricyclic pyrimidine compounds of the present invention have favorable inhibitory activity against JAKs as shown above.

ASSAY EXAMPLE^(a) 2 Signal Assay in Human Whole Blood

To be a effective pharmaceutical compound for the target diseases of the present invention, especially for rheumatoid arthritis, it is more favorable that the compounds indicate excellent inhibitory activity against JAKs in human whole blood. Inhibitory activity against JAKs in human whole blood can be assessed by, for example, STAT phosphorylation assay in human whole blood as described below.

Compounds are added at the various concentrations to human whole blood which is collected from healthy volunteers and preincubated for 30 minutes. Next, cytokine such as IL-2 or IL-6 is added to the mixture and incubated for 15 minutes. Cytokines can be purchased, for example, from PeproTech Inc. Cytokines are added to mixture at 100 ng/mL as final concentration. The mixture including the blood cells are hemolyzed, fixed, permeabilized, washed, and resuspended in stain buffer. BD Cytofix/Cytoperm® solution (manufactured by Becton, Dickinson and Company (BD)), for example, can be used to hemolyze, fix, and permeabilize. Staining buffer (manufactured by BD), for example, can be used as stain buffer according to each protocol issued by BD. Fluorescence-labeled anti-phosphorylated STAT antibody and fluorescence-labeled anti-CD3 antibody are added to the cell suspension and incubated for 30 minutes. Then, cells are washed and resuspended in stain buffer. Fluorescence-labeled anti-phosphorylated STAT antibody and fluorescence-labeled anti-CD3 antibody can be purchased, for example from BD, and final concentration of antibodies can be determined according to each protocols issued by BD. Fluorescence intensity of fluorescence-labeled cells in cell suspension is detected by flow-cytometory. Because the detected fluorescence intensity is proportional to the concentration of the phosphorylated STAT protein in CD3 positive cells, inhibitory activity against STAT phosphorylation by the compounds can be calculated from the ratio between the above mentioned fluorescence intensity and the blank fluorescence intensity which is measured simultaneously without the compounds. From the plot of logarithm of the compound concentrations and the inhibitory activities, the IC₅₀ value can be calculated.

ASSAY EXAMPLE^(a) 3 Inhibition of Proliferation of Erythro-Leukemic Cell Line

The inhibitory activity of the tricyclic pyrimidine compounds of the present invention on cell proliferation mediated by JAK signal can be assayed using a human erythro-leukemic cell line, TF-1.

TF-1 cells can be purchased from ATCC (American Type Culture Collection). TF-1 cells can be expanded in RPMI1640 media containing 5% FBS and 1 ng/mL GM-CSF (Granulocyte Macrophage Colony-Stimulating Factor) using a CO₂ incubator (5% CO₂, 37° C.). At the assay, TF-1 cells washed by PBS (Phosphate Buffered Saline) are resuspended in RPMI1640 media containing 5% FBS, and dispensed in 96-well culture plate at 1×10⁴ cells/well. Compounds at various concentrations are added to the cells and preincubated for 30 minutes, and then cytokine such as IL-4 or IL-6 is added to the cells. Culture plates are incubated using a CO₂ incubator (5% CO₂, 37° C.) for 3 days. Cell proliferation can be assayed using WST-8 reagent (Kishida Chemical Co., Ltd.) according to instructions by the manufacturer. The formazan pigment is generated by the addition of WST-8 reagent solution to each well of the culture plates and the subsequent incubation in a CO₂ incubator (5% CO₂, 37° C.) for 4 hours, and then detected by measuring the absorbance at 450 nm with a microplate reader. From the plot of logarithm of the compound concentrations and the inhibitory activities, the IC₅₀ value can be calculated.

REFERENCE SYNTHETIC EXAMPLE^(b) 1 Methyl 4-methylpyridin-3-ylcarbamate

Potassium tert-butoxide (10.3 g, 92.5 mmol) in tetrahydrofuran (25 mL) was stirred at 23 to 27° C. for 30 minutes, and dimethyl carbonate (4.67 mL, 55.5 mmol) was added while the temperature was kept at 35° C. or below. To the reaction mixture, 3-amino-4-methylpyridine (5.00 g, 46.2 mmol) in tetrahydrofuran (40 mL) stirred at 32 to 38° C. for 90 minutes was added dropwise at 20 to 35° C. over 2 hours with stirring. The resulting reaction mixture was cooled to 15 to 20° C., stirred with water (25 mL) at 25° C. or below for 1 hour and extracted with tetrahydrofuran. The organic layer was azeotropically distilled with toluene under reduced pressure to a volume of about 50 mL and stirred at 23 to 27° C. for one day. The precipitated solid was collected by filtration, washed with toluene and dried under reduced pressure to give the title compound as a brown solid (6.77 g, yield 88%).

REFERENCE SYNTHETIC EXAMPLE^(b) 2 Methyl rac-(3R,4R)-1-benzyl-4-methylpiperidin-3-ylcarbamate

Methyl 4-methylpyridin-3-ylcarbamate (30.6 g, 184 mmol) and 5% rhodium-carbon (12 g) in acetic acid (120 mL) were stirred at 72 to 78° C. under a hydrogen atmosphere (70-80 psi). After disappearance of the starting materials was confirmed by NMR, the reaction mixture was filtered, and the filtrate was concentrated under reduced pressure to give a concentrate (40.9 g). The concentrate (31.7 g) was stirred with benzaldehyde (21.5 mL, 202 mmol) in toluene (184 mL) at 20 to 30° C. for 30 minutes. The resulting toluene solution was added dropwise at 30° C. or below to a toluene (40 mL) solution of sodium triacetoxyborohydride (9.35 g, 44.0 mmol) stirred at 20 to 30° C. for 1 hour. The resulting reaction mixture was stirred for 2 hours, adjusted to pH 6-7 with 3 M aqueous sodium hydroxide at 20° C. to 30° C. and extracted with toluene. The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give a brown oil (38.1 g) containing the title compound. The oil was used for the next step without further purification.

REFERENCE SYNTHETIC EXAMPLE^(b) 3 rac-(3R,4R)-1-Benzyl-4-methylpiperidin-3-amine

Crude methyl rac-(3R,4R)-1-benzyl-4-methylpiperidin-3-ylcarbamate (2.3 g) in concentrated hydrochloric acid (15 mL) was refluxed for one day under heating and allowed to cool to room temperature. The hydrochloric acid was removed under reduced pressure, and the reaction mixture was partitioned between chloroform and saturated aqueous sodium chloride.

Now, a pharmacological assay of the tricyclic pyridine compounds of the present invention will be described.

Assay Example^(b) 1 Enzyme Assay

JAK1, JAK2, JAK3 and Tyk2 were purchased from Carna Biosciences, Inc. As the substrate, LANCE Ultra ULight-JAK1 Peptide (manufactured by PerkinElmer Co., Ltd. (PE)) was used. Dilute solutions of compounds and enzymes in assay buffer (50 mM HEPES pH7.5, 1 mM EGTA, 1 mM MgCl₂, 2 mM DTT, 0.01% Tween20) were dispensed into wells of a 384-well black plate. After 5 minutes of preincubation, dilute solutions of the substrate and ATP (adenosine triphosphate) were added at a final concentration of 100 μM, and the plate was incubated at room temperature for 2 hours. After addition of a termination reagent containing EDTA (ethylenediamine tetraacetic acid) at a final concentration of 10 mM, LANCE Eu-W1024 Anti-phosphotyrosine (PT66) (manufactured by PE) was added, and after 1 hour of incubation, the fluorescences were measured with ARVO-HTS. From the plot of logarithm of a compound concentration and inhibitory activity, the IC₅₀ was calculated. The results of JAK3, JAK1, JAK2 and Tyk2 enzyme assays of the compounds of Synthetic Examples^(b) are shown in Tables^(b) 78 to 81. “*” in the Tables indicates IC₅₀>1 μM.

The tricyclic pyridine compounds of the present invention have favorable inhibitory activity against JAKs as shown above.

Assay Example^(b) 2 Signal Assay in Human Whole Blood

To be a effective pharmaceutical compound for the target diseases of the present invention, especially for rheumatoid arthritis, it is more favorable that the compounds indicate excellent inhibitory activity against JAKs in human whole blood. Inhibitory activity against JAKs in human whole blood can be assessed by, for example, STAT phosphorylation assay in human whole blood as described below.

Compounds are added at the various concentrations to human whole blood which is collected from healthy volunteers and preincubated for 30 minutes. Next, cytokine such as IL-2 or IL-6 is added to the mixture and incubated for 15 minutes. Cytokines can be purchased, for example, from PeproTech Inc. Cytokines are added to mixture at 100 ng/mL as final concentration. The mixture including the blood cells are hemolyzed, fixed, permeabilized, washed, and resuspended in stain buffer. BD Cytofix/Cytoperm® solution (manufactured by Becton, Dickinson and Company (BD)), for example, can be used to hemolyze, fix, and permeabilize. Staining buffer (manufactured by BD), for example, can be used as stain buffer according to each protocol issued by BD. Fluorescence-labeled anti-phosphorylated STAT antibody and fluorescence-labeled anti-CD3 antibody are added to the cell suspension and incubated for 30 minutes. Then, cells are washed and resuspended in stain buffer. Fluorescence-labeled anti-phosphorylated STAT antibody and fluorescence-labeled anti-CD3 antibody can be purchased, for example from BD, and final concentration of antibodies can be determined according to each protocols issued by BD. Fluorescence intensity of fluorescence-labeled cells in cell suspension is detected by flow-cytometory. Because the detected fluorescence intensity is proportional to the concentration of the phosphorylated STAT protein in CD3 positive cells, inhibitory activity against STAT phosphorylation by the compounds can be calculated from the ratio between the above mentioned fluorescence intensity and the blank fluorescence intensity which is measured simultaneously without the compounds. From the plot of logarithm of the compound concentrations and the inhibitory activities, the IC₅₀ value can be calculated.

Assay Example^(b) 3 Inhibition of Proliferation of Erythro-Leukemic Cell Line

The inhibitory activity of the tricyclic pyridine compounds of the present invention on cell proliferation mediated by JAK signal can be assayed using a human erythro-leukemic cell line, TF-1.

TF-1 cells can be purchased from ATCC (American Type Culture Collection). TF-1 cells can be expanded in RPMI1640 media containing 5% FBS and 1 ng/mL GM-CSF (Granulocyte Macrophage Colony-Stimulating Factor) using a CO₂ incubator (5% CO₂, 37° C.). At the assay, TF-1 cells washed by PBS (Phosphate Buffered Saline) are resuspended in RPMI1640 media containing 5% FBS, and dispensed in 96-well culture plate at 1×10⁴ cells/well. Compounds at various concentrations are added to the cells and preincubated for 30 minutes, and then cytokine such as IL-4 or IL-6 is added to the cells. Culture plates are incubated using a CO₂ incubator (5% CO₂, 37° C.) for 3 days. Cell proliferation can be assayed using WST-8 reagent (Kishida Chemical Co., Ltd.) according to instructions by the manufacturer. The formazan pigment is generated by the addition of WST-8 reagent solution to each well of the culture plates and the subsequent incubation in a CO₂ incubator (5% CO₂, 37° C.) for 4 hours, and then detected by measuring the absorbance at 450 nm with a microplate reader. From the plot of logarithm of the compound concentrations and the inhibitory activities, the IC₅₀ value can be calculated.
